10Molecules in solids are completely stationary.
Heating increases molecular vibration.
Cooling causes expansion of solids.
Water behaves like other substances at all temperatures.
At 4°C, water has minimum volume.
Increase in temperature generally causes contraction.
Gas molecules are very close to each other.
Release of thermal energy decreases temperature.
